A method of delivering a compound to a plant to inhibit an ethylene response in the plant, the method comprising the step of contacting a complex formed from a molecular encapsulation agent and a compound having the following structure
- wherein n is a number from 1 to 10 and R is selected from the group consisting of hydrogen, saturated or unsaturated C1 to C10 alkyl, hydroxy, halogen, C1 to C10 alkoxy, amino and carboxy, with a solvent capable of dissolving the molecular encapsulation agent, and thereby liberating the compound from the molecular encapsulation agent so that it can contact the plant.
